Josef Mengele

June 7, 1985

Age: He was born March 16, 1911. If he is alive, he is 74.

Education: He studied philosophy in Munich, took his medical degree at the University of Frankfurt am Main.

History: In his 20s, and already a Nazi, Mengele worked at Germany's new Institute of Hereditary Biology and Race Research where he specialized in the study of twins and racial pedigrees. During World War II he joined the Waffen SS and served as a medical officer in France and Russia. In 1943, aged 32, he was appointed Nazi SS chief doctor at Auschwitz.

Last seen: In 1945 Mengele escaped from a British internment hospital and, with the aid of false papers, fled via Rome to Buenos Aires. He was granted Paraguayan citizenship in 1959 but it was revoked under international pressure in 1979 and he disappeared.

His crimes: Mengele was wanted for supervising the gassing at the Auschwitz death camp and conducting experiments on thousands of children. He conducted pseudoscientific research into presumed racial differences, including anomalies of giants and dwarfs, hunchbacks and other deformities. He was especially interested in medical experiments on twins in order to find ways of creating a race of blue-eyed Aryans.
